Question

Please Help!!!Select two points to define a line where the polygon will break
into two pieces.
Which formulas will be needed to find the area of the
possible shapes that make up this composite figure?
Check all that apply.
A=s²
A = 1/2bh
A=1/2pie r2
A=1/2(b1+bw)h
A=bh

​

Answer 1

Given:

Rectangle and semi-circle

To find:

Area of formulas for the composite figure

Solution:

The first shape is rectangle.

Rectangle have base and height.

Area of rectangle :

Area = base × height

$A=bh$

The second shape is semi-circle.

Area of the circle formula:

$A=\pi r^2$

Semi-circle is half of the circle.

Area of semi-circle formula:

$A=\frac{1}{2} \pi r^2$

The formulas needed to calculate the composite figure is $A = bh, \ A=\frac{1}{2} \pi r^2$.
